If JK . is formed by J(-7,-8) and K(1, 4), determine if L(-9,5) lies on the perpendicular bisector. Part A
What elements do you need to show to confirm that Point L is on the Perpendicular Bisector of JK ?

Part B
Find the elements you described in Part A. Explain your work.

Part C
Verify if Point L is on the Perpendicular Bisector of JK. Justify your conclusion.

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .
